I was looking around for official load data for some Hercules/Alliant 2400 powder. Couldn't find any .300 AAC Blackout data on their website, so I wrote them. Thought I would share their reply. I know the standard has been H110 and Lil'Gun, but those are not easy to obtain powders. Also Power Pro 300-MP seems to be coming on strong and here is the data for that.

Remember if you are using this...work up your loads.

Dang a 300 BO case filled to the top is 20gr of 2400. Just filled one. 16 grains looks like it will be slightly compressed by the bullet. I am useing 221 fireball brass converted to 300 Whisper aka BO.
I shoot 24 grains of 2400 out of my 45-70. Curious to see how this powder works out for you.
